Description

E. NeumannE. Neumann

Die Erfindung bezieht sich auf einen Hochleistungsschalter, bei dem zur Unterstützung des Unterbrechungsvorganges Löschflüssigkeit durch den beweglichen, hohl ausgebildeten Kontakt mittels eines in dem Hohlkontakt gleitenden Kolbens kurz vor und während der Kontakttrennung· zwischen die Kontaktstellen gepreßt wird. Erfindungsgemäß erfolgt der Antrieb des Pumpenkolbens in dem bewegliehen Hohlkontakt durch eine mit dem Kolben verbundene Druckplatte, die außerhalb des Rohrkontaktes angeordnet ist und den Kolben bei der Ausschaltbewegung des Kontaktes bzw. seiner Traverse in Richtung· der Unterbrechungsstelle treibt, weil die Schaltflüssigkeit die Druckplatte an der Mitbewegung hindert.The invention relates to a high-performance switch in which to support of the interruption process extinguishing liquid through the movable, hollow Contact by means of a piston sliding in the hollow contact shortly before and during the Contact separation · is pressed between the contact points. According to the invention, the Drive of the pump piston in the movable hollow contact by one with the piston connected pressure plate, which is arranged outside of the pipe contact and the Piston during the switch-off movement of the contact or its cross member in the direction of the Interruption point drives because the switching fluid moves the pressure plate with it hinders.

Wie im Ausführungsbeispiel gezeigt ist, wird bei der Ausschaltbewegung der Traverse e infolge der durch, die Schalterflüssigkeit ausgeübten Bremskraft der Kolben c in den HoMkontakt b getrieben. Zu diesem ■Zwecke ist der Kolben c unten mit einer Platte ώ versehen, die den Gegendruck beim Ausschalten aufnimmt.As shown in the exemplary embodiment, when the cross member e is switched off, the piston c is driven into the HoM contact b as a result of the braking force exerted by the switch fluid. For this purpose, the piston c is provided with a plate ώ at the bottom, which absorbs the counterpressure when it is switched off.

Als feststehender Kontakt kann ein an sich bekannter Rundkontakt α verwendet werden. In Abb. ι ist der Flüssigkeitsschalter eingeschaltet dargestellt. Abb. 2 zeigt den Schalter kurz nach der Kontakttrennung. Die Flüssigkeitsspülung, die bereits vor der Kontakttrennung einsetzt, richtet sich auch gegen die Haftstelle des Lichtbogenfußpunktes,· sie wird erst beendet, nachdem der Kontaktabstand groß genug ist.A known round contact α can be used as the fixed contact. In Fig. Ι the liquid switch is shown switched on. Fig. 2 shows the switch shortly after the contact has been separated. The flushing of the liquid, which already begins before the contact is separated, is also directed against the trapping point of the arc base point, it is only ended after the contact distance is large enough.

Die vorliegende Spüleinrichtung läßt sich mit geringen Mehrkosten in jedem Flüssigkeitsschalter und insbesondere auch in mehrpoligen Schaltern anbringen, ohne daß deren Aufbau wesentlich geändert wird.The present flushing device can be installed in any liquid switch with little additional cost and especially also in multi-pole switches without significantly changing their structure.

Patentanspruch:Claim: Flüssigkeitsschalter, bei dem zur Löschung des Lichtbogens ein Flüssigkeitsstrahl durch den beweglichen, hohl ausgebildeten Kontakt mittels eines in ihm gleitenden Kolbens zwischen die Kontakte kurz vor und während der Kontaktöffnung gepreßt wird, dadurch gekennzeichnet, daß der Kolben (c) außerhalb des Rohrkontaktes mit einer Druckplatte (d) verbunden ist, die den Kolben bei der Ausschaltbewegung des Rohrkontaktes bzw. der mit ihm verbundenen Traverse (e) infolge der auf sie durch die Schalterflüssigkeit ausgeübten Bremskraft in den Hohlkontakt in Richtung der Unterbrechungsstelle liineintreibt. Liquid switch, in which, to extinguish the arc, a jet of liquid is pressed through the movable, hollow contact by means of a piston sliding in it between the contacts shortly before and during the contact opening, characterized in that the piston (c) outside of the pipe contact with a pressure plate (d) is connected, which drives the piston into the hollow contact in the direction of the interruption point in the direction of the interruption due to the braking force exerted on it by the switch fluid when the pipe contact or the cross member (e) connected to it is switched off.
